Interview with wangyuntao of China Academy of information technology: digital and real integration enables the prosperity and development of cultural industry

　　 Virtual space 、 Next generation Internet 、 Number twin 、 Expanding reality …… These familiar keywords are related to the meta universe , There is no authoritative definition of the concept of metauniverse , Different participants continue to enrich their meaning with their own understanding . From the Internet giants, they have stepped up the layout of the meta universe , To where the metauniverse was first written “ the 14th Five-Year Plan ” Industrial Planning , With the acceleration of the integration of virtual world and physical world , Take root in reality ,“ Promote reality with emptiness 、 Strengthen reality with emptiness ” The direction of development is gradually clear .

The original title ： Meta universe ： future ？ A scam ？ Firmly rooted in reality 、 In the direction of "virtual, strong and real" 　

　　2021 year 10 month , Social media giant Facebook Renamed Meta（ element ）,“ Meta universe ” It was successfully selected into the national language resources monitoring and research center “2021 Top 10 Internet terms of the year ”, The whole world seems to be talking about the meta universe . What is the key technology behind the meta universe ？ What will it build for the development of cultural industry “ stage ”？ recently , Deputy chief engineer of China Institute of cloud computing and communications 、 Senior engineer Wang Yuntao accepted 《 People's post and Telecommunications 》 An exclusive interview with a newspaper reporter , focusing AR（ Augmented reality ） and VR（ Virtual reality ） technology , Answer the questions related to the prosperity of cultural industry driven by immersive technology development . With “ Immersive ” Technology enriches the experience of cultural activities 　　 The reporter ：AR and VR Technology is the core technology to create immersive experience , How is its development ？ What are the characteristics of technology itself ？ 　　 Wang Yuntao ：AR and VR Technology driven by industry , Continuous progress and maturity . Technical aspects , actually AR and VR There are two completely different routes ：VR It aims to create a fully immersive virtual space completely independent of the real world , and AR Focus on creating a virtual interactive experience around the real world . 　　 about VR Come on , Generally, the industry believes that it has four elements ： More perceptual 、 immersion 、 Interactivity and autonomy , But in fact, at present VR Technology focuses on Immersive interaction at the visual level , The key technology is mainly composed of dynamic environment modeling technology 、 Real time 3D graphics generation technology 、 Stereoscopic display 、 Sensor technology 、 It is composed of application system development tools and system integration technology . 　　 about AR Come on , At present, the main focus is on the enhancement of vision , It mainly includes unarmed interaction （ For technology Voodoo Dolls） Interact with ray casting tracks （ For technology HOMER）. It should be noted that ,AR The equipment is diverse , Including but not limited to helmets 、 Handheld touch screen device 、 Projector 、 Desktop, etc . 　　 The reporter ： At present , What new attempts are there in immersive live experience ？ 　　 Wang Yuntao ： At present, the meta universe has made active exploration in immersive experience , In consumer entertainment 、 Culture, education and industrial manufacturing 、 Smart city and other aspects have excellent industrial practice . In the social sphere , People's display has changed from traditional web materials to real-time interaction with virtual avatars , If in 《 Fort night 》 Live concert , A talk show hosted by virtual idol Mei Shitian 《 May said 》 etc. ; In the field of office , Microsoft 、Meta And so on MR（ Mixed reality ）、VR The collaborative office platform of ; In manufacturing ,BMW And Nvidia Under development based on Omniverse A new generation of virtual factories ; In the medical field , Foreign countries have launched through XR（ Expanding reality ） Technology provides an anatomical view , The first hospital of Shanxi Medical University has also developed avatar virtual diagnosis and treatment system for the treatment of depression . Develop new needs with culture “ customized ” technology roadmap 　　 The reporter ： Which technical characteristics closely meet the needs of the development of cultural industry ？ The new demand for the development of cultural industry forces digital technology to provide what kind of services ？ 　　 Wang Yuntao ： In the new era of digital economy , There are also new demands for the development of cultural industry ： diversity , And more convenient communication and sharing . The core of digital technology empowerment , Is to promote the digital transformation of the cultural industry , say concretely , By digitizing cultural resources , Thus, tangible or intangible cultural heritage can be 、 Cultural relics 、 Arts and Crafts 、 Resources such as museum collections are seamlessly transferred to the virtual world , It will not only show the diversity of cultures to the whole world , More and more fixed resources can benefit people at a lower cost . 　　 In fact, this also poses a great challenge to digital technology . One is the ability of data acquisition . Whether for the acquisition of graphics and images , Or a quantitative collection of physical phenomena , All need camera equipment 、 Comprehensive improvement of data acquisition capability represented by sensing equipment . The second is the ability of digital modeling . Reconstruction of cultural objects in the virtual world , It has developed from pixel level reconstruction to atomic level reconstruction , 3D object oriented modeling technology is its core . 　　 The reporter ： What is the future direction of immersive experience ？ How will the development of digital technology help enrich the experience of cultural activities ？ 　　 Wang Yuntao ： In the future, the development of meta universe in immersive experience will follow the development of artificial intelligence 、 The development of computer vision technology , And the continuous improvement of computing power . 　　 There will be three characteristics ： First, more and more excellent material and cultural heritages of the physical world will be “ transfer ” To the virtual world , The degree of reduction and simulation will be higher and higher ; Second, the cultural industry of the virtual world will become more and more developed , Intelligent interaction with virtual cultural heritage will be more immersive 、 Intelligent experience ; The third is based on virtual places 、 Virtual digital people, etc “ Native digital culture ” It's going to shine , The cultural industry will also focus on the digital transformation from the physical world to the virtual world , To fully build a virtual world based “ Native digital culture ” And stride forward .

Technical observation

Metaverse origin

　　“ The dream of Zhuang Zhou was Hu die , Hu die is so vivid , Self metaphor and , I don't know Zhou ye .” B.c. 300 year , Taoist Zhuang Zhou Mengdie , Thoughts on the linkage between dream and reality ,2022 The cosmic heat of the Yuan Dynasty , Focus on the digital world 、 Integrated development of the physical world . Although I'm familiar with it , But the meta universe has not been widely recognized as a precise definition , Now it's just a concept that's still developing , Different participants constantly enrich its meaning with their own understanding . 　　 Meta universe metaverse yes meta and universe The combination of ,meta From ancient Greek , There are multiple meanings , Can be expressed in the middle 、 Transformation 、 transcend . at that time , Athenians call the study of tangible things physics（ physics ）, The research on intangible things is called metaphysics（ Metaphysics ）,meta It comes from here , Primordial “ element ” take “ transcend ” The meaning of . that , Why use ancient Greek roots with rich meanings ？ Perhaps the best thing is that it can't be seen through at a glance . It's a new concept , Contains ideas for the future , It also needs the continuous innovation and development of underlying technology to support this idea . 　　 At the Institute of electrical and Electronics Engineers （IEEE） Search on website “metaverse”, The earliest conference paper “Avatars a/spl grave/ la Snow Crash”, On 1998 Published by scholars in the field of human modeling and simulation , The study analyzed Neil · Science fiction by Stephenson 《 An avalanche 》 in “ avatar （Avatar）” On the outside 、 race 、 Body movements 、 Emotional characteristics, etc . Science fiction 《 An avalanche 》 The story of created an online world parallel to the real world , In the real world, people who are geographically isolated from each other through their own “ avatar （Avatar）” Communicate and entertain . Sanskrit Avatar At the religious level, it refers to the transformation from God to man “ Descend to the world ”, In the context of the game, it means the virtual identity used by the player . 　　“ Yuancosmos is the next generation of Internet applications and social forms produced by integrating a variety of new technologies .” Professor Shenyang of Tsinghua University proposed , Meta universe “ Realize space-time expansibility based on extended reality technology and digital twins , be based on AI And the Internet 、 The man-machine integration of natural man and robot , Based on blockchain 、Web3.0、 Digital collection /NFT And so on ”. From the perspective of Technology , The realization of the idea of meta universe involves network and computing technology 、 Artificial intelligence 、 Display technology and blockchain technology , It covers a wide range , The relevant technology is not yet mature , The corresponding virtual and real economic system still needs a long time to verify and adjust . 　　 The concept of meta universe may have originated in ancient Greece , It has something to do with the idea of science fiction , It also seems to be closely related to the development of scientific and technological innovation .2021 year 11 month , The stocks of listed enterprises in China rise when they announce that they have entered the yuan universe , The meta cosmic plate has 117 companies , Attracted the attention of the CSRC . The piling up of concepts and the continuous enrichment of meaning , Make the already vague definition more difficult to understand , It also makes us think about whether the metauniverse is the future or a scam . Based on the principle of inclusiveness and prudence , The computing power network on which the metauniverse depends 、 Artificial intelligence and other key technologies , We give firm support , We will continue to deepen the construction of information infrastructure , For the social system at the virtual level and the unknown concept that is still in an unknown state , We should correct the problems in development in time and build a solid safety bottom line , Avoid fooling around under the guise of Technology .
